Appnqation inea August 10,1901. sfitl No. 71,547. (Numana Y To all whom it may concern.-

Be it known that I, HARRY STILLSON HART, a citizen of the United States,vresidin'g jat Ghif. cago, in the county of Cook and Stateof Illinois, have invented certain new and useful Improvements in Dumping-Cars, of which the following is a specification.

The invention relates to that class of du mping-cars that is provided with hopper-bottoms arranged longitudinallyof the car, and particularly to the construction thereof by which ballast or other material may be dumped be-v tween the tracks, to either side, or both, as maybe desired, all of which will more fully vhereinafter appear..

The principal object of the invention is to provide a simple, economical, and efficient dumping-car-with hopper-bottoms arranged to dump material between the tracks or to each side thereof.

Further objects of the invention will appear from an examination of the drawings and the following description and claims.

The invention consists principally in a car of the class set forth in which there is combined with the usual frame portion a plurality of hopper-bottoms arranged longitudinally Y of the car, so as to dump material between bottom to discharge material to each side ofV Athe tracks.

The invention consists, further, in a car of the class set forth having, in combination with the usual frame portion, a main large hopperbottom arranged longitudinally of the car, withits apex at or near the central 'portion thereof and having a dumping-door near its apex, and smaller supplementary hopper-bottoms arranged longitudinally of the car to each side of the main hopper-bottom and provided with dumping-doors forming a portion ofthe inclined bottoms, so as to discharge material to each side of thetrack.

The invention consists, further and finally,

in the features, combinations, and details of construction hereinafter described and claimed. y

AIn the accompanying drawings, Figure lis aplan View of a car constructed 1fn-acc'ordance with these improvements; Fig.2, a longitudinal sectional viewtaken through the car on line 2 of Fig. l looking in the direction of the arrow and showing the hopper-bottoms with their discharging-doors arranged inopen discharging position; Fig. 3, a'similarview Ato that shown in Fig. 2, with the dischargingdoors locked in their closed position.' In the art to which this invention relates it is well known that there are two classes of dumping-cars, one arranged to discharge material at or near the. centerand between the supporting-tracksand the other to` discharge material to each side of the car and outside ofthe su pporting-tracks. It is alsowell known that Vit is highly desirable to have'a car which can discharge material either. between the tracks or to each side thereof and which can alsobe used for discharginga portion of thema# terial to eitheror both sides of the track and the balance, if necessary, between the tracks. The principal object, therefore, of this inventionis to provide a car with a. plurality of discharging-hoppers by which a portion of the material may be first discharged to either or both' sides of the -track fand the balance between the tracks, or the larger part of the material between the tracks and the balance at each side of the tracks. f

ist@` 'In illustrating'and describing this inven-'-'. tion I have only illustrated and described these improvements I make a car provided with side boards aand end boards b, supported on a frame portion constructed in any usual manner and which needs no further or detailed description here. The end boards may be inclined downwardly and inwardly, if necessary, though to meet ordinary circumstances and conditions in this type of car they can be vertically arranged.

In order to provide for the discharge of material between the tracks or to each side thereof, I make a main hopper portion composed of centrally-inclined bottom portions c and d, arranged longitudinally of the car and inclining down toward the central portion thereof, so that the apex of such hopper-bottom is arranged substantiallyin line with the longitudinal center of the car. One of these inclined hopper-bottom portions, d, is provided with a discharge-door e, arranged near the apex thereof, so that when such door is opened in the position shown in Fig. 2 the material may be passed ont through the opening formed thereby and discharged in a pile of the desired size between the tracks. VThis door vis held in its closed position by means of a chain j', arranged so as to be'wound around a shaft g, which shaft may be supplied with pawl-and-ratchet mechanism (not shown and Vwell known to those skilled in the art) for the purpose of rotating the shaft and holding it in its locked position. An examination of the drawings will show that the opening of the discharging-door in the central hopper will not discharge all of the material in the car, but will leave small portions or piles to each side of the car, which it is necessary to discharge. These piles at each side of the car provide for a certain amount of material which may be dumped to each-side on supporting-tracks and in the case of ballast for ballasting the road-bed Outside of the tracks. In order to provide for discharging this material, the car is provided with two supplementary hopper-bottoms of smaller capacity than the main central one, one of which is arranged to each side of the main central hopper-bottom. These hopper-bottoms are formed of two inclined hopper-bottom portions h and h', one of which is in fixed position, and swinging portions e' and fl', which are swingingly held in position and also form discharging-doors. From this description of construction it will be seen that i the doors may be swung into the position shown in Fig. 2 and all of the remaining material dumped out through the opening formed thereby. The dumping-doorsz'and 11' are held in their locked position by means of chains j and j', which are wound around shafts 7c and k. These shafts maybe provided with square ends, (not shown,) if necessary, to receive cranks (not shown) for turning the same, all of which is well known to those skilled in the art.

The principal advantages incident to a car constructed in accordance with these improvements arc that the larger amount of material, if necessary, can be dumped outside of the track for the ballasting of the road-bed ontside of the tracks, or the hopper-bottom at the central portion of the car can be first opened and the larger amount of material discharged between the tracks, the residue and smaller amount being left to be dumped to each side of the tracks to be used as may be desired, either for filling of the embankment or ballasting the road-bed.

I claim- 1. In a car of the class described, the combination of a frame portion, a central hopperbottom,and two side hopper-bottoms arranged longitudinally of the car and provided with discharging-doors to discharge material between and outside of the tracks, substantially as described. y

2. In a car of the class described, the combination of a frame portion, a main hopperbottom arranged longitudinally of the car at or near the central portion thereof and p rovided with a discharging-doorarranged at its apex to discharge material centrally of the car, a supplementary hopper arranged outside and to each side of the main hopper-bottom and longitudinally of the car and provided with discharge-doors to discharge the material to each side of the car, substantially as described.

3. In a car of the class described, the combination of a frame portion, a main relatively large hopper-bottom arranged longitudinally of the car With its apex arranged at or near the longitudinal center thereof'and provided with a discharging-door at or near its apex to discharge material centrally of the car, and relatively smaller hopperbottoms, one at each side of the main hopper-bottom and provided with discharging-doors for discharging material to each side of the car, substantially as described.

4. In a car of the class described, the combination of a frame portion, a main relatively large hopper-bottom arranged longitudinally of thefcar with its apex arranged substantially at the longitudinal center thereof, a swinging door in one of its inclined portions to provide for the discharge of material between the supporting-tracks, a supplementary and relatively smallerhopper-bottom arranged at each side of the hopper-bottom and 1ongitudinal of the car composed of a xed inclined portion forming one side and a swinging portion forming the other side of such 4hopperbottom and a discharging-door therefor, substantially as described.

5. In a car of the class described, the combination of a frame portion, a main relatively large hopper-bottom arranged longitudinally of the car with its apex arranged substantial] y at the longitudinal center thereof, a swinging door in one of its inclined portions to provide for the discharge of material between the supporting-tracks, a supplementary and relatively smaller hopper-bottom arranged ab disohargngdoors in their looked position,
